I'll give you my wifi password so you can sit on the porch & surf all you want.
For example, one residential ISP just released a statement apparently clarifying their policy regarding "unlimited" plans [1]:
“Customers are free to go crazy and use as much data as they want. We have some customers using nine terabytes per month on our residential unlimited plans which shows just how unlimited they really are."
9TB at home?!
Personally I use a different ISP at my house: I have ADSL2+ and get a quota of 260 GB per month for about $50. This is a "naked" service so I receive it via a copper line whose regular landline dial-tone service has been disconnected.
